What you see here is a magic square, much like the addition and subtraction squares you may have used as a child. These magic squares are even more talented, as they all follow the rules of the card game SET®. To learn how to make one with ease, read on. 
SET® cards contain four properties: color, shape,
number of objects, and shading. The rules state for each
property, they must all be equal, or all different. For example, if
we look at the top row of the square, we see three different colors,
three different shapes, three different numbers, and three different
types of shading within the objects. Need more examples? Any line on
the magic square yields a set.



A few examples will convince you that this method works. Not only
does the magic square work but it can be theoretically proven through
a mathematical model. This model makes an easy
proof of the magic square, as well as answer any questions about how
SET® works.
